Sharks spiral-shaped intestines resemble a Nikola Tesla invention

Samantha Leigh/California State Sharks have spiral-shaped intestines that work in a similar way to an unusual valve designed by Nikola Tesla. Studying their anatomy could help improve industrial fluid-pump technology. Most animals have tubular intestines that use muscle contractions to push food along like squeezing a tube of toothpaste. But sharks slowly channel their meals through spirals without needing muscles to push the food. Their intestines are also shaped in a way that only allows food to flow one way – like a performance-enhanced Tesla valve, says Samantha Leigh at California State University Dominguez Hills. “Sharks have all these different little tweaks to the Tesla valve design that could be making them more efficient,” she says.

New 3D images of shark intestines show they function like Nikola Tesla s valve

Even less is known about how they digest their food, and the role they play in the larger ocean ecosystem. For more than a century, researchers have relied on flat sketches of sharks digestive systems to discern how they function and how what they eat and excrete impacts other species in the ocean. Now, researchers have produced a series of high-resolution, 3D scans of intestines from nearly three dozen shark species that will advance the understanding of how sharks eat and digest their food.
